abscissa writes "It took them almost 18 years, but the solution to checkers has been found. You can't win at checkers unless your opponent makes a mistake! Now all that remains is elusive solution to chess! With more possible ways to play a game of chess than there are electrons in the known universe, it does seem far off. Until then, study your perfect opening books for checkers!"

Roland Piquepaille writes "What happens when you compress water in a nano-sized space? According to Georgia Tech physicists, water starts to behave like a solid. "The confined water film behaves like a solid in the vertical direction by forming layers parallel to the confining surface, while maintaining it's liquidity in the horizontal direction where it can flow out," said one of the researchers. "Water is a wonderful lubricant, but it flows too easily for many applications. At the one nanometer scale, water is a viscous fluid and could be a much better lubricant," added another one."

Ken Erfourth writes "The Inquirer.net is running a story about what they consider two powerful indications that Vista is failing in the marketplace. One, Dell has reintroduced PCs running Windows XP on its website due to customer demand. Two, Microsoft is conducting a worldwide firesale on a bundle of Microsoft Office 2007/WindowsXP Starter Edition. According to Inquirer.net, at least, these are signs of serious problems selling Vista. Are we seeing the stumbling of the Microsoft Juggernaught with the slow adoption of Windows Vista?"

Londovir asks: "Recently, our school board made the decision to block Wikipedia from our school district's WAN system. This was a complete block — there aren't even provisions in place for teachers or administrators to input a password to bypass the restriction. The reason given was that Wikipedia (being user created and edited) did not represent a credible or reliable source of information for schools. Should we block sites such as Wikipedia because students may be exposed to misinformation, or should we encourage sites such as Wikipedia as an outlet for students to investigate and determine the validity of the information?"

Roland Piquepaille writes "The launch of the Orbital Express mission, with its two satellites ASTRO and NextSat, the first one servicing the other, was widely covered a month ago. But what is happening in space now? In 'Robotic satellite servicer rehearsal underway in orbit,' Spaceflight Now reports about the progress done. A week ago, the two satellites were able to link to each other to operate the first transfer of hydrazine fuel from ASTRO's propellant tanks into NextSat. This weekend, ASTRO's ten-foot-long robotic arm is going to be used to move objects to NextSat. But what does it mean for international satellite operators when they need help with their space birds? Will they use a system designed for U.S.'s DARPA? "

Roland Piquepaille writes to let us know about research into producing palpable maps for the blind. Scientific American has the story of Greek researchers who produce 3D "haptic" maps that "use force fields to represent walls and roads so the visually impaired can better understand the layout of buildings and cities." Two separate systems produce haptic output from standard video and from 2D maps. The systems have been tested on a small number of users. Currently the devices that interpret the "force fields" for sight-impaired users are not portable, and so the systems are most appropriate for doing research before, e.g., visiting a new city.

Roland Piquepaille writes "Researchers from Illinois and Florida are developing a networking system which will create virtual representations of real people to improve our knowledge. They will use artificial intelligence and natural language processing software to enable us to interact with these avatars. The goal of the project, sponsored by the National Science Foundation (NSF), is to give us the possibility to interact with these virtual representations as if they were the actual person, complete with the ability to understand and answer questions. We should see the results at the beginning of 2008 — if the researchers succeed."

writertype writes "Although Blackboard is used to communicate between students and professors at virtually all of PC Magazine/Princeton Review's top 20 wired colleges, when run under a Vista environment users can see glitches. Moreover, IT departments told PC Mag that if Blackboard is used with Vista plus IE7, students can't communicate via the software. When asked why, Microsoft ... waffled. Blackboard says they'll have a fix in place by summer. Meanwhile, are there any other common college apps that Vista fails to work with?"

TunesBoy writes "Only a couple of days after being shipped, the Apple TV is already being modified in a variety of ways. A thread at Something Awful discusses installing VLC, and a dedicated site, AppleTVHacks.net, has appeared and is cataloging hacks including a hard-drive upgrade tutorial. Did Apple intend for the Apple TV to be so easy to upgrade and hack?"

Krishna Dagli writes "Two Ph.D. students at the University of California at Berkeley say that Daylight Saving Shift will not do any good or create any energy savings. We are already spending money for software upgrades in the name of saving energy and after reading following article I wonder has congress really studied the impact of DST shift? " I also read some back story on the concept; OTOH, I found TiVo's suggestions that I manually change everything on my Series 1 device to be somewhat...insulting.

Stu writes "'A world without net neutrality is one devoid of intellectual development' said Sir Tim Berners Lee in a presentation to congress last week. Well, now there's a computer model that uses game theory to back that forecast up. Developed at the University of Florida, the model shows that everyone loses if the IPs get their way — even, eventually, the IPs."

abscissa writes "Essjay, the one of highest level ups on Wikipedia who lied about his credentials in an effort to "protect his identity" (though he later announced his real name, age, and place of residence), announced that he will be leaving Wikipedia. He claimed to have several advanced degrees in theology and even went so far as to pretend to be a professor and write in support of a student (that content has now been permanently erased). He had been promoted to a paid Wikia position by Jimbo Wales, but after an outpouring of anger he was asked to resign by Jimbo (who claimed not to have all the facts until very recently)."

sandoz writes "Macenstein has up an interesting article with some evidence that running Safari seems to slow down unrelated programs. While the speed with which a browser renders a Web page is an important measure, the difference between browsers is usually a matter of a few seconds at most. To my mind, a more important measure of speed is how a browser affects the overall speed of your system." Some responses to the article suggest that memory handling in WebKit may be the culprit. The Safari developers have already responded to this article on the webkit.org blog. They explain why the slowdown might be occurring and how it's (probably) already been fixed in the nightly build. And they request more minimal test cases.

coondoggie sends us a NetworkWorld story on the prospects for Apple gaining market share in the corporation. A number of factors are helping to catch the eye of those responsible for upgrading desktops and servers, the article claims: "Apple's shift to the Intel architecture; the inclusion of infrastructure and interoperability hooks, such as directory services, in the Mac OS X Server; dual-boot capabilities; clustering and storage technology; third-party virtualization software; and comparison shopping, which is being fostered by migration costs and hardware overhauls associated with Microsoft's Vista." On this last point, one network admin is quoted: "The changes in Vista are significant enough that we think we can absorb the change going to Macs just as easily as going to Vista."
